I have a free version of Daytona Road course, v1.45 dx11. It has some very weird idiosyncrasies. When loading the track, the track map starts filling in at sector two, progresses to three and finishes with sector 1. It does have the extended pit lane speed limit to near the exit and the AI follow at pit speed to the proper point. But the track tells you to turn off your pit speed limiter at the old pit out line. The AI fortunately ignore this message but if you release it is a sure speeding penalty. And it seems prone to crashing back to the main rF2 menus.
Maybe someone can take a look. Maybe the location of the xSectors is not correct pos. or the objects (xsectors) occupy some common limit
v.1.45 dx11 is the workshop version https://steamcommunity.com/sharedfiles/filedetails/?id=2382581965 as i said it's a broken version (they updated the old heavy and problematic v.1.27 version. for a good work they need to redo the track update starting from v.1.28) try v.1.28 on ISR, it works well, less heavy and no ctd
